Wall Of Berlin is the ninth track on Prince's 33rd studio album Lotusflow3r.
Basic tracking took place on 19 November 2004, during a three-and-a-half hour session with Michael B. on drums and Sonny T. on bass at Paisley Park Studios in Chanhassen, Minnesota that also yielded 3121, From The Lotus..., ...Back 2 The Lotus, Colonized Mind, Love Like Jazz, Planet Earth, Guitar as well as a song possibly called Shameless.
A tape photographed in Prince's vault at Paisley Park Studios lists Wall Of Berlin as 19 November 2004, which alludes this is the exact date for all of the songs in this sessions.
In an August 2006 interview, Michael B. said [they recorded] eleven or twelve tracks in three and a half hours that night. On a different occasion he later indicated that this was the last recording session they did with Prince for a while after that.
The phrase used in the title, "wall of Berlin", was also used in the track 3121, also recorded with Michael B. and Sonny T., so it is possible these tracks were recorded during the same set of sessions. The track was premiered on Los Angeles radio station Indie 103 on 18 December 2008, along with Crimson And Clover, Colonized Mind and 4ever. The party noises heard at the end of the track are, in fact, the beginning of the album's following track, $, for which recording details are listed in its respective song entry.
The "wall of Berlin" is a reference to the Berlin Wall, which divided the cities of West Berlin and East Berlin (and the countries of West Germany and East Germany, respectively) until its fall in 1989.
